4 Claims. (Cl. 30-40) "This present invention relates to the general art of Safety razors, and more particularly to a safety razor which is characterized by having a rectangular housing or handle member which is itself the magazine for the storage of razor blades and is provided at one end with means for positioning and holding a safety razor blade in position for satisfactory shaving.

A large number of various types of razors have been provided in the past, each adapted to accept a small steel blade sharpened on either one or two edges. The usual practice has been to have the blades so that they are held in shaving position singly, and, when the blade being used has deteriorated to the point where a new blade is desirable, then the razor is manually manipulated so that the mechanism of the razor will release the used blade and make available the space for acceptance of a new blade. This operation is normally a slow one and, as a result, many attempts have been made to provide re'peatingtypes of razors.

,This present invention is of the repeating type, in that it provides in a housing or hand, storage space for a large number of razor blades which are spring-fed up to the using end. This is believed to be an outstanding characteristic of this invention and to distinguish, as far as now known, from the various types of repeating razors formerly employed. Quite a number of razors have been provided in which, in the head assembly immediately adjacent the using blade, provision may be made for the storage of a limited number of blades, on the order of ten or a dozen normally, which can be used sequentially as desired. In certain types of razors the blades have been stored with their cutting edges disposed parallel to the longitudinal axis of the handle, and normally at right angles to the final position of use of the blade in the razor head.

This latter type, as well as the former types that have been observed, are characterized by requiring rather involved mechanism in order to transfer the blades from the storage magazine to the shaving head. Many times the dexterity required on the part of the user to satisfactorily operate the razor has been sufiicient to greatly retard the sale of this type of razor, even though it has many desirable attributes. In this present razor it is believed that a great many of the undesirable characteristics of the repeating razors formerly used have now been avoided or eliminated and a very simple mechanism provided, that is very easy to use and admits of the storage of an unusually large number of razor blades which are spring-fed up to the point of use.

A principal object of this present invention, therefore, is to provide a repeating safety razor which employs the handle portion of the razor to house the razor blades in a manner retaining them substantially parallel to the blade in use.

A further object of this present invention is to provide a repeating razor in which a large number of razor blades may be stored ready for use.

ice

A further object of this invention is to provide a safety razor in which each blade, as it is brought into use, is accurately and definitely positioned in the optimum position of use. J

A further object of this invention is to provide a repeating mechanism for the ejection of used razor blades and the re-supplying of new blades, which is very simple in its operation, to the end that it can be expected to operate for long periods without servicing and does not require any special training or attention on the part of the user.

Further objects, advantages and capabilities will be apparent from the description and disclosure in the drawings, or may be comprehended. or are inherent in the device.

In the drawings:

Figure 1 is a perspective view, partly in section and partly in exploded. relationship to illustrate the essential properties of this present invention.

Figure 2 is an enlarged cross-sectional view taken along the plane of line 2 of Figure 2, with the cutting plane being perpendicular to the wide face of the razor housing.

Figure 3 is an enlarged outside elevational view of the end of the razor where the shaving head is employed.

Figures 4 and 5 are fragmentary cross-sectional views taken substantially along the line 4-4 of Figure 3 and illustrating two stages in the ejection of a used razor blade.

Figure 6 is a typical cross-sectional view as taken along the line 66 of Figure 1 and illustrating the magazine and follower mechanism employed in this razor.

Figure 7 is a fragmentary cross-sectional view of the filling end of the razor blade magazine, illustrating the form of joint employed, as taken along the line 7-7 of Figure 1.

Figure 8 is a front elevation taken along the line 8-8 of Figure 2 with the cover member removed.

Referring more particularly to the disclosure in the drawings, the numeral 10 designates the main housing or handle of this razor, which is generally of rectangular form having a loading end closure plate 12, the top wall 14, the bottom wall 16 and the side wall portions '18 and 20. Any suitable material may be employed in forming this handle, although it has been found that the modern yieldable plastic materials are the most satisfactory. It is desirable that side wall 20 be somewhat longer than side wall 18, so that the shaving end of the device will normally hold the razor blade at an angle with respect to the longitudinal axis of housing 10. A satisfactory angle for the presentation of the razor blade is normally between 8 and 20. However, the angularity, as illustrated, is best adapted to a right-handed shaver, whereas a left-handed shaver would find greater usefulness with the angle reversed. As a result of the difference in handling of the razor by rightand left-handed people, it may be desirable to have the shaving head at right angles to the longitudinal axis, if a very inexpensive model is desirable, to the end that a dealer would only have to stock one type. v

The shaving end of housing 10 is further angularly arranged with respect to the plane \of the walls 14 and 16 of the housing, and this is probably best illustrated in Figures 2 and 3. With this arrangement the razor blade B is normally presented at a most convenient angle with respect to the face being shaved. As a guide or rest for the shaving end of the razor during use, a rib 23 disposed transversely by handle 10, is preferably provided. I

Withing housing 10 is provided the magazine space for a plurality of razor blades B, and in this connection,

it is desirable to point out that the present razor of normal hand-filling dimensions can adequately house a hundred razor blades, and this is believed to be an adequate supply for a long trip. In normal use, however, blades would be introduced into the magazine in smaller quantities in conformity to the usual sales package. The razor blades are engaged by a blade follower member 30, which is spring-urged toward the shaving head end of the housing by a suitable spring 32. Various types of springs might be employed; however, for cheapness of manufacture and for all around general satisfaction, the folded type of fiat spring, as illustrated in Figure 1 particularly, has proven quite acceptable. Spring 32 is anchored to the closure plate 12 and the follower 30 by a plurality of rivets illustrated in Figure 6 at 34. The blades themselves stand substantially transversely in housing 10 and at right angles to walls 14 and 16. The urging force of spring 32 actually causes the blades to assume a position parallel to the blade in use in the shaving head.

The size of the housing should be such as to form a convenient enclosure for the blades, with just enough freedom for their easy passage through the razor, normally cover 40, which serves as a blade abutment and guard, is secured along its top margin and right-hand margin, as viewed in Figure 1, to the housing member 10. This provides a slot at 42 extending across the face of member 40 so that the razor blades edge can protrude through this slot into its shaving position. Normally, however, the blade is carried in a position in prolongation of the mass of blades, as illustrated in Figure 2. Similarly, at the left-hand end of head member 40 another slot is provided at, 44, so that, when the blade is to be discarded, it can be withdrawn through this opening.

The withdrawal of'a used, razor blade is achieved by a slidable hook member having a preferably metal hook portion 46 and a longitudinally stepped slider member 48 adapted to engage a coacting slot 50 in member 40, which is stepped at 54 in Figure 5, it will be noted that the hook member 46 is retracted by means of the slider member 48, and this is the normal carrying or storing position. When it is timely to eject the blade, however, it is slid to the left as viewed in Figure 4, so that the hook portion of the member 46 may overrun the end of blade B and engage its end surface. Slider 48 may then be moved to the right as viewed in Figure 4, and the blade to be discarded will be passed out through opening 44. The amount of this protrusion is limited by the length of slot 50. This slot could be substantially the full length of member 40, except for strengthening or tying together portions as 52. However, it has normally been found most convenient to have the blade merely carried a reasonable distance so that it can then be gripped by the thumb and forefinger and withdrawn manually.

With the used razor blade out of position, spring 32 would normally raise the mass of razor blades toward the shaving head, with the endmost one in engagement with guard member 40. It would normally, because of the pressure of the spring, be in alignment with these blades. In order to bring the blade into usable position, pressure is applied to depressable button 60, and this is pressed downwardly. In so doing pressure is applied by the seating follower member 62 over sufiicient length of the blades upper margin and moves it in a manner so that both ends progress an equal amount. The blade is then pressed down to the dotted-line position shown in Figure 2 at 64 where, when pressure is released on button 60, the-spring member 61 is retracted and spring 32, applying pressure to the mass of blades B, seats-the razor blade intended for next use in the recessed portion of head member 40. This is of the same cross section as slot 44, and in Figure 4 the view is thesame for both the ejection slot and the positioning slot for the razor blade in use. When the blade is seated in slot, it then abuts slot margin 64 and, with the pressure of spring 32 against it, the blade is then held in firm operational position. The downward movement of blade B is limited by two abutment pins 66, against which the cutting edge of the blade comes to rest. These pins are positioned so as to engage the corner portion of the blade and thus form an additional safeguard so that the extreme corner of the sharp edge of the blade cannot engage the shavers flesh.

In Figure 7, an end sectional view is shown of the joint between handle 10 and cover plate 12. Such an interlocking joint can only be successfully employed with plastic material having considerable resiliency and thus permit snapping the short rib 24 into a coacting groove in the side walls 18 and 20. A coin slot 22 is provided to facilitate removing cover 12.

It is believed that it will be clearly apparent from the description and the disclosure in the drawings that the invention comprehends a novel construction of repeating razor.
